What the authority record establishes

ISO 16739-1 specifies the IFC data schema and exchange structure for construction and facility-management information.

Voluntary unless adopted through contract or another authority

The exact official title, issuing body, jurisdiction, version or application record, and linked source define the scope of this page. Readers should not transfer the authority's status to a commercial product or infer transaction-, patient-, system-, site-, or organization-specific applicability from this summary.

Why it matters to this market

It helps buyers ask which schema, model view, entities, properties, classifications, geometry, relationships, validation, and exchange evidence a construction product actually supports.

Implementation questions

  • Which entities, products, populations, transactions, systems, sites, or jurisdictions are actually within scope?
  • What is binding, what is guidance, and what is a technical or consensus standard?
  • Which publication, adoption, effective, application, transition, and enforcement dates differ?
  • Who owns legal, clinical, quality, regulatory, policy, or operational interpretation?
  • How will a source revision affect open work and historical decisions?

Interpretation boundary

IFC support does not establish complete exchange, model quality, configured interoperability, or suitability for a particular project use.
